I might depend on how you have the sub connected, but normally, no. You'd adjust the frequency on the sub so that it picks up where your speakers roll off, which can be quite tricky. Sometime the sub may have a crossover so you can control what frequencies are handled by the sub and what are handled by your speakers, but even with such a setup, I had my speakers handling upper bass and the sub mainly filling in the frequencies that my speakers can't reach.
